Question

which of these factors may affect a persons blood alcohol concentration?
○ gender
○ race
○ blood type
○ age

Explanation:

To determine which factor affects blood alcohol concentration (BAC), we analyze each option:

• Gender: Biological differences (e.g., body composition, enzyme activity) between genders influence alcohol metabolism, so gender affects BAC.
• Race: There’s no consistent scientific evidence that race directly affects BAC (eliminated).
• Blood type: Blood type relates to blood cell antigens, not alcohol metabolism (eliminated).
• Age: While age can influence metabolism, the question likely prioritizes gender here (or the options may have a typo, but gender is a well - established factor).

Answer:

A. gender
